Existing Diesel Legislation Abolished for Construction Machinery On Sites

Red Diesel in Construction Machinery

Following on from an increase in living prices, and diesel costs skyrocketing, new diesel legislation has been introduced, directly affecting the construction industry. For anyone that uses red diesel in construction machinery, then pay attention, because this affects you!


The government has announced new upcoming changes to the current diesel legislation, which will come into effect from 1st April 2022. Anyone currently using rebated red diesel will no longer be permitted to use it on construction sites in the UK. The only legal usage will be within agriculture, horticulture, fish farming, forestry, rail projects and also on golf courses.

Chancellor Rishi Sunak announced the upcoming changes during Budget 2020. The aim was to reduce the amount of businesses using polluting fuels, and paying for the standard rate of diesel instead.  

Unfortunately this will mean paying more to power your construction machinery. However, the new legislation has been put in place to meet the government’s net zero plans, and tackle climate change.


Red diesel also known as Gas Oil contains a red marker dye, which is where it gets its name. The dye helps differentiate it as rebated fuel, and is easily identifiable if the wrong fuel is used. It is primarily used for most off road transport, including:

  • Tractors
  • Diggers
  • Marine Vessels
  • Stationary engines

99% of UK construction sites are actively using red diesel, and will have to swap to white diesel instead. 

It can however still be used after 1st April 2022 if it is already in the tank prior to this date. Nonetheless, machines should only be refilled with white diesel. So what’s the difference we hear you ask?


One of the main differences between red and white diesel is the fuel duty rate. So many individuals use red diesel due to its fuel duty rate of 11.14 pence per litre. Whereas white diesel only costs 57.95 pence per litre. 

The only other difference is the colour. The red dye is added to the rebated fuel to stop anyone trying to use red diesel to fill up their cars. As any driver would know it is illegal to fill up a conventional car with the rebated fuel, so the dye will catch you out! It is only legal for off-road machines as mentioned above to use red diesel up until 1st April 2022.
